[Newbies] Squeak Guilt

I'm in a position where I want to learn Squeak/Smalltalk because it's cool, but I find myself thinking that I should spend my time working on something that might actually advance my career. I used to be a Java Programmer, but am now a Build Engineer, so I don't directly program anymore. I feel that I should be keeping my Java skills up... but that just isn't as spiffy

Anyone else in this boat? Is there a Squeak Support Group? A 12 step program? Anyone have a good rationale why I can go ahead and spend my time on Squeak without feeling guilty? :) :)
